Avocado Salmon Sandwich

Preheat broiler to about 475F. Peel and slice avocado and sprinkle with part of the lemon juice.

Divide avocado slices evenly over the bottoms of the hamburger buns.

Drain salmon and break into chunks. Divide evenly over avocado slices, and sprinkle with remaining lemon juice. Top with second halves of the buns, then with cheese slices. Sprinkle with sesame seeds. Broil about 8 inches from heat until cheese melts and the sandwiches are heated through. Garnish with dill pickles.
